METHOD OF MAKING WHEELS.

Specification of Letters Patent.

Patented May 12, 1914.

Application filed July 15, 1912. Serial No. 709,471.

To all whom it mag concern Be it known that I, ALBERT Kon'rmr, a citizen of the l nited States, residing at Buffalo, in the county of Erie and State of New York, have invented new and useful Improvements in Methods of Making Wheels, of which the following is a specification.

This invention relates to buffing, polishing or cleaning wheels, and has for one of its objects the making of the same with a minimum amount of waste of the textile or other material.

In the accompanying drawings, Figure 1 represents a portion of the textile material divided into sections in the manner that I prefer to cut the same. Fig. 2 represents one of the said sections detached from its contiguous members. Fig. 3 represents a wheel as I prefer to build up the same from the above mentioned sections.

I first determine the size or diameter of my wheel; then take the radius thereof and lay off on the material 1, an are 2 with a radius 3, as shown in Fig. 1. A second and similar are 2 with a like radius 3 is joined to the first are 2. tangent thereto, but re versed. A plurality of the said arcs are then joined to the above mentioned arcs forming a wavy or sinuous line 7. Above and below the said line 7 are drawn other and similar lines 5, 6, 8, 9 and the like dividing the material into wavy or sinuous bands 4. Lines 10 preferably straight divide the spaces between the parallel lines into quadrilateral sections 11.

One of the sections 11 is shown detached in Fig. 2; and in Fig. 3 these out and detached sections are shown overlapping one another and forming the wheel: the deeper layers of sections being staggered to the said i upper layer. I preferably sew the sections together near their inner peripheries as at 12, and then clamp them together in any suitable manner.

It will be noted that the outer periphery of the wheel requires no rounding off as the arcs 2 are originally of the correct curvature; and as the arcs lie along the direction of the fibers of the material. the entire periphery of the wheel will be 'of uniform strength. Also it will be seen in Fig. 3 that the prolongations 15 of the sides 10 of the sections 11 preferably converge. at say 13, below or beyond or eccentric to the center 14 of the. wheel, and therefore are not radii as 3 of the same: and that while the outer peripheries of the said sections are concentric to each other and to the wheel itself. the inner peripheries thereof are eccentric.

I do not limit n'iyself to the use of textile fabrics as I may use any other material. Nor do I limit myself to the exact shape as shown as I may make the sectionslonger or wider; the sides 10 thereof may be curved, and the sections 11 may or may not be contiguous. But as I am entitled to all the equivalents that fairly fall within the scope of my claim. I will not mention many other changes that might be made without departing: from the spirit of my invention.

I claim The herein described method of manufacturing a wheel for the purpose specified, comprising cutting: flexible material into sinuous bands bounded on both sides by a plurality of parallel reversed tangential arcs of a circle of substantially the same curvature as that of the outer periphery of the wheel. cutting the said hands into sections across the said ares at an angle to the perpendicular, the prolongations on the right and left hand sides thereof converging, to a center eccentric to the center of the wheel, placing the said sections in a circle overlapping each other, and finally fastening the same together.

ALBERT KORTUM.
